I recently replaced my computer. I am unable to retrieve my clients 2020 detail tax information.

You cannot copy the data files from one computer to another.  You need to do a backup/restore.

I find it easier to COPY the Directories where the files are located and restore those same directories on the new computer. This way your Dates are not changed for each file. Once you do this you only have to do a home base maintenance for each Form in use.

One thing to remember is to load each state you used for the year into the new computer.
